As a follow-up to this previous thread, the baptism of the wife of Joseph Thibodeau, Marie-Anne Martin, was not found, either. She would have been born around 1801 according to her census age. It seems no one born at St-Basile between 1799 & 1803 is recorded.

Yes, I found the marriage as well. Very interesting. There are no baptisms of any children of this couple in any of the on-line registers between 1795 and 1800. It stands to reason there were two or three children born to the couple during that period. To French Catholics of that time, the church was all encompassing. To not baptise their children is unthinkable. I guess this is one of those rare circumstances where the records were either not recorded or lost.

Check this interesting page at URLhttp://search.ancestry.com/Browse/view.aspx?dbid=1110&path=S.St-Basile.1792-
1837.44&sid=&gskw=&cr=1. Looks like there were no sacraments performed at
St-Basile between 1799 and 1803, if I read it correctly (I never attended
French school, unfortunately). They were covered at St-André as suggested in
another post. I checked 1800 (24 pages) St-André and nothing. Looks as
though the priest "covered" things by performing late baptisms, and he got
the birth days incorrect for one or both of them. It would seem likely that
since he had exact month and days, that one was off by a year. Probably
asked how old each was then subtracted incorrectly. So my plan is to use the
Simon Thibodeau birth date with explanation. It would seem Firmin/Fermin was
the older brother; perhaps he was born in 1799 (I'll check PRDH). Thanks for
an interesting and helpful discussion on this.
